Filmmaker Ken Burns is hard at work on a documentary on country music according to his partner, Dayton R. Duncan, reports the Tennessean.According to Duncan, Little Jimmy Dickens and legendary musician/producer Harold Bradley have both been interviewed for the project.

“We’ve done films about uniquely American ideas and things that help tell us who we are as Americans — baseball and national parks and jazz, and essential American icons like Mark Twain and Lewis Clark,” he said. “Country music really combines both of those things. It’s uniquely American. It’s an American art form that helps you understand what America is.”

According to Duncan, the country music documentary will likely take about five years to make. Don’t expect stars like Garth Brooks or Taylor Swiftto be featured, though. “You’ve got to have an arm’s length of time for it to be history, and that’s usually about a generation,” he said. “It’s history we’re telling and not what’s happening today.”
